أَنَا أَبُو النَّجْمِ وَشِعْرِي شِعْرِي
I am Abu al-Najm, and my poetry is indeed my poetry.
The repeated phrase “my poetry is my poetry” can have a rhetorical force beyond repetition: in context it emphasizes the distinctive character or excellence of the speaker's verse.
This illustrates that repetition is not necessarily idle in eloquent speech. It does not, however, make the poetic example identical to the theological argument for objective realities.
One form of repetition may intensify an assertion; another may clarify what is genuinely disputed.
